Hi I’m trying the smartmatrix libraries but I always get this error:
C:\Users\House\Documents\Arduino\libraries\SmartMatrix3\src/SmartMatrix_Impl.h:26:24: fatal error: DMAChannel.h: No such file or directory

forwarding with arduino using esp32 dev module in the examples I find it as incompatible …
Where am I doing wrong?
thanks
Rocco.

i used the teensylc branch with MultiRowRefreshMapping.ino as you descripted above.
Looks like:#include <SmartMatrix3.h>
|

#include “SmartMatrix_Impl.h”
|

#include “DMAChannel.h” (this h-file is tennsy specific, isn’t it?)
and get the same compile error: DMAChannel.h: No such file or directory
There is no ESP32 specific strapping for the includes.
Many thanks for another help,
Andreas

i used the Hub75 branch, this workes fine! Also on master there is no ESP32 solution available (as far as i could see).
I have the ESP_V0 Shield and this works pretty stable.
Many thanks for your good work, i wished i could program as good as you…
What do you think about an ESP32 branch or merge all changes back to master?
This would make it easier for newbies…
